Necessary in environments that regularly use weighing devices, calibration weights guarantee that measuring standards are met. Working to correct slight mechanic changes caused by transporting or excessive instrument handling, these tools guarantee that results remain accurate. The recessed grip or hanger styles are constructed of corrosive resistant metals that withstand cleaning solvents used in uncompromised performance preparations. Calibration weights are available in various masses and tolerances to maintain any analytical balance or laboratory scale resolution and sensitivity.
